FENDER FOR STOVE-PIPES.

SPECIFICATION forming part of Letters Patent No. 420,999, dated February11, 1890.

Application filed September 25, 1889. Serial No. 324,994. (No model.)

To all whom it may concern:

Be it known .that we, JONATHAN JOHNSON and EDMUND H. PAOKER, citizens ofthe United States, residing at Lowell, in the county of Middlesex andState of Massachusetts, have invented certain new and usefulImprovements in Fenders for Stove-Pipes; and we do declare the followingto be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompany.- ingdrawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to a fender whereby flames in stoves and otherheating devices which are connected with a chimney by an ordinarystove-pipe are protected from backdrafts.

Where stove-pipes Of the ordinary kind are used, it has been found thatwhen backdrafts are created in the chimney by the opening Or closing ofdoors or other means the products of combustion are forced into theroom. These drafts are sometimes of sufficient force to extinguish theflame, especiallyimmediately after it has been kindled. This isespecially so in heat-radiators where gas is used as a fuel. This causesmuch inconvenience, and in case of the radiator is dangerous on accountof the gas escaping.

The invention relates to a device for overcoming this difficulty; and itconsists, essentially, in a main chamber inclosing a deflector andhaving short sections of pipe protruding from both ends for connectingit with the portions of pipe between which it is to be placed.

It further consists in certain details of construction and arrangementof parts, hereinafter more fully described.

In the accompanying drawings, in which similar letters of referencedesignate corresponding parts, Figure 1 is a plan view of the device.Fig. 2 is a transverse cross-section. Fig. 3 is a longitudinalcross-section.

Referring to the drawings by letter, A designates the main chamber,preferably rectangular in shape, and has projecting from both endsections of pipes B B for connecting it with the two portions of thepipe between which it is to be inserted. The upper end of the chamber isclosed, having the pipe B inserted in it in any suitable manner. Thelower end of the chamber is left open and has projecting from it thepipe B, which extends upward into the main chamber a considerabledistaneeabout one-third of the length of .said chamberand is fastened inplace by flector, when so fastened, will pass at an inclination over theupper opening of the pipe .13. The lower end of the deflector is bent,so

as to be parallel to the side of the pipe to which it is attached, andextends a short distance below the mouth of the same. The deflectoris inwidth a mean between the breadth of the chamber and the diameter of thepipe B. The outer edges 0 c of the deflector are turned up at rightangles to the main surface for the purpose which will be stated furtheron.

After the fender has been placed in position for operation and. a firestarted, the smoke from the same will ascend and pass through the pipe13 and strike against the deflector, passing arounditinto the upper pipeB. It has been found that the deflector presents but a slight impedimentto the passage of the smoke. If, however, a back-draft should becreated, it would strike against the deflector, and pass along betweenthe same and the walls of the chamber out into the room. The upturnededges 0 c of the deflector prevent the smoke from passing under the sameand entering the lower pipe.

Having described our invention, What we claim, and desire to secureLetters Patent for, 1s-
